Humans can analyze other humans, remembering their faces and knowing if they are a threat through their strong sense of perception. In an article written by Amelia Stymacks published by National Geographic, it becomes evident to believe that crows, one of our world’s smartest birds, have “an uncanny memory for human faces—and can remember if that particular person is a threat” (Stymacks). In this essay, the relation between the perception of humans and crows will be discussed through a discovery found by National Geographic on the intelligence of birds.
